The Peyton Manning sweepstakes continued Sunday as the free-agent quarterback paid a visit to the Arizona Cardinals amid reports that the Denver Broncos were emerging as the favorites after their visit with the four-time NFL MVP Friday night.

Manning spent nearly seven hours at Arizona's headquarters and training facility. He waved and smiled at cheering fans as he walked from the building to coach Ken Whisenhunt's white SUV. With the coach at the wheel, Manning waved again as the SUV pulled through the security gate and past the loud supporters.

Team president Michael Bidwill, general manager Rod Graves and offensive line coach Russ Grimm were also at the facility during Manning's visit. Receiver Larry Fitzgerald spent a few hours with Manning in the morning before departing for an Australian vacation.

NFL Network insider Jason La Canfora reported the quarterback was set to return to Miami following his visits with the Broncos and Cardinals, and could meet soon with the Dolphins, according to league sources.

As the field narrows among the suitors for Manning, other teams -- beyond the Broncos, Cardinals and Dolphins -- are still relatively in the dark about the process and are uncertain they will get a meeting, league sources told La Canfora.

Barring unforeseen circumstances, La Canfora reported, Manning is not scheduled to meet with more than three teams and wouldn't sign with another team without a prior meeting. League sources tell La Canfora that Manning has given no indication that he will throw for teams yet and may get the contract without it.

A source who had spoken to Manning prior to his visit with the Cardinalstold ESPN that "his gut is that Manning is leaning toward Denver."
